Abstract Superhydrophobic coatings have been used to solve the problems of oil spills polluting water sources and resource shortages. However, short service life superhydrophobic limit their widely application. In this work, a novel fluorine‐free, self‐healing, coating composing polydimethylsiloxane (PDMS), polydopamine (PDA) modified halloysite nanotubes (HNT), beeswax (BW) are fabricated for oil/water separation as well fog‐water collection. Herein, PDA stabilizes dispersion HNT in coating, meanwhile enhances adhesion nanoparticles on fabric surfaces. The as‐fabricated occupied contact angle 163.1°, demonstrating exceptional characteristics. exhibited superior efficiency over 99.5% outstanding collection rate 990 ~ 1208 mg cm −2 h −1 . Owing presence BW, demonstrated remarkable self‐healing properties can regain superhydrophobicity after 100 wear cycles with just heating treatment. Therefore, facile strategy has great potential large‐scale manufacturing multifunctional coatings.

Abstract Superhydrophobic surfaces can effectively inhibit the growth of droplets and reduce attachment, thus inhibiting formation frost. In this paper, using dimethyldimethoxysilane-modified silica nanoparticles, a superhydrophobic coating with contact angle 165.73 ± 1° rolling 2 was successfully prepared by secondary spraying method, chemical composition substrate surface morphology were characterized means FT-IR, EDS, SEM. A visualization test rig constructed to investigate condensation droplet characteristics on across various tilt angles (0°to 90°), cold temperatures (-1 ℃ 5 ℃), humidity levels (45% 75%). The experimental results revealed that as increases, forces acting condensed change, resulting in higher frequency merging, jumping, slipping. Furthermore, decrease temperature accelerates droplets. Under varying conditions, nucleate grow more rapidly high environments, where they exhibit larger coverage area despite having relatively small mean radius.

Steel structures located in subtropical marine climates face harsh conditions such as strong sunlight and heavy rain, they are extremely corroded. In this study, a waterborne coating with excellent corrosion resistance, hydrophobic ability, high-temperature resistance high density was successfully prepared by using modified nanoscale titania powders grafted polymers. The effects of three modifiers on nanoparticles coatings’ properties were studied independently. experimental results showed that the activation index modification employing methacryloxy silane reached 97.5%, which achieved best effect at 64.4 °C for 43.3 min. exhibited effect, drop contact angle 115.4° heat up to 317.2 °C. application steel under maritime coatings demonstrated corrosion, temperatures sunlight, maximum service life five years. Economic analysis indicated that, considering conservative three-year effective lifespan, could save more than 50% cost compared conventional industrial coatings. Finally, strengthening mechanism polymer analyzed.
